Brightly colored hair?

I personally don't dye my hair like because it's looked down upon where I live, and I'm too self conscious to deal with that, and I don't even know if it would look good on me. On girls though I think its incredibly attractive, and sometimes it says a lot about them if they are willing to do that even in an area like where I live.

So what are your thoughts on it? Like it? Hate it? Would you wear it? Why/why not?
